Have you ever had issues with electromagnetic interference (EMI)? Well now you can track down the source with this simple DIY, which lets you make your EMI detector using an Arduino. Now you can hunt for the culprit without spending a lot of money.

Well DiddyBorg is here and how! It is the most powerful RPI robot, yet available. It is said to be able to climb inclines of 45 degress. It can surf any indoor or outdoor terrain, like shown in the video. You can use it to build super cool gadgets. DiddyBorg can be mounted with a camera or connected to a gaming console and do a 360.You can buy the kit online and follow the detailed instruction list, which comes with pictorial representation, to assemble it. To get it up and running, you though need quite a few softwares. The turorial assumes, you’re using the latest version of Raspbian and are connected to the internet.

Let me start by pointing out that this DIY was invented by someone who was an Arduino amateur and didn’t have a programming background. Good news, right! He isn’t an electrical engineer neither a musician. He experimented and voila! Although you do need the determination and a few skills like drafting or soldering. You can always learn these things, so let’s get started.

So after we told you that you can handle your light system using an app or flicking your phone, now we bring to you a way to talk to them. Yes. We are not kidding, this time either! You can talk into your phone and switch on or off a particular light system. Let’s see how.

‘Old is gold’. We never want to get rid of our old gadgets, has been further proved with this yet another DIY which can fix your vintage radio with Raspberry Pi. The main theme of the project, is the same. Keep the old school look and make the update the functions. 

We have come across a lot of a lot of instruments, made from Arduino, but none like this one, so far. This device, makes beautiful music, literally. Take a look at the video, below.

DORA is a four wheeled robot which explored the surroundings and environments in a way which combines telepresence and virtual reality. No, we are not talking about ‘Dora, The Explorer’. DORA is Dextrous Observational Roving Automaton.

This DIY lets you control your railway model with Arduino Mega Microcontroller. This is a huge project, so has been split in parts. This one here tells you how to create a controller/throttle with a basic acceleration and braking process with a 12V DC PWM output.

To see the exact configuration of each component, head over to the source link. This project was compiled on Linux operating system using Ansible, which is an open source SSH based management tool. It can execute ad hoc commands and predefined playbooks on multiple nodes.

Navio+ is an inexpensive HAT for Raspberry Pi and provides a complete range of sensors, GPS, servo outputs and inputs, A2D, I2C, SPI and UART interfaces. This lets you have a Raspberry Pi compatible APM. Now APM, is the autopilot system which is also known as ArduPilot. It is the most popular open source drone system. 

Antenna analyzer is a tool used for fine tuning of antennae and troubleshooting it. Now you can build an Arduino based Antenna Analyzer at home, for a low frequency application for less than 30MHz. 

This is DIY dew controller, made using Arduino Nano. It functions as a standalone device, from a local or a remote computer or from remote windows. The user can toggle the switches to override the power on the dew straps and operates on 12DVC.

Well, a device which tells you that we’ve been rubbing it wrong, all this while. Here is an automatic board eraser which can do the job for you, without you moving from your place. It is a normal magnetic eraser with motors and wheels, which can be mounted on the board and do the task.

Well, here is a technology, which is wearable. Literally! It’s an LED shirt which lights up when you are in vicinity of a technical device. It might sound like one of those random tshirts with light on it, but read on to be amazed. Matt Martin designed this amazing shirt which tells us that we are always surrounded by technology. It might be wireless or invisible, but we are always connected. 

This DIY will let you have a Christmas Star Light, with a twist. It is GSM controlled and changes patterns, colours and frequency according to the text messages. The inventor likes to call it, ‘interactive tradition’, we think it’s quite apt. 

This DIY is right out of a Bond movie. It’s a tilt triggered coffee cup and the project also tells how you can keep your cover form blowing. We think, it is pretty cool. It uses Arduino Uno Rev 3, a TTL serial JPEG camera module, a SD card shield, resistors, LEDs, and a Mesmic 2125 2 axis accelerometer, to the make the whole thing, tilt triggered.

Bitcoin is a peer to peer payment system, where users can transact with each other without needing an intermediary. The network nodes verify the transaction and it is hence termed as decentralized virtual currency. There is an ongoing debate whether Bitcoin is a currency or not but this DIY Bitcoin Mining technique comes with a warning. You are obviously investing at your own risk. 

To connect your Raspberry Pi 2 to a screen you just need an HDMI port but what if you want a small portable screen? A small screen can be easily embedded into a project and is also easy to power using a USB port of the device. This DIY will show you how to connect an Adafruit HDMI 5″ display backup to the Raspberry Pi 2.

A Nixie Tube or cold cathode display is a device, used for displaying information using glow discharge. This electronic device consists of a wire mesh and cathodes, shaped like symbols. You power it and the number is clearly visibly, thanks to the glow discharge. This tube is filled with neon, mercury and argon, at low pressure. You can get them online. And they look beautiful!
